Introduction Human Area network

An emerging field of communications technology with the potential to offer significant advantages to Pervasive computing. (military operations, smart home etc).

Overview of Technology

(1/2)

Is the idea of “Pervasive computing” really old?

Mark Weiser, 1952-1999

Father and founder of ubiquitous computing.

-1988

Ubiquitous computing -“era that replaces PCs with invincible computers embedded into everyday objects.”

Overview of Technology

(2/2) Pervasive Computing Network Technologies: WPAN • Wi-Fi - [ IEEE 802.11 ].

• Bluetooth - [ IEEE 802.15.1 ].

• ZigBee - [ IEEE 802.15.4 ].

• and other RF technologies.

“Adaptive” Computing Realm

Human Area Network

• • • Its a new technology which uses human body as transmission media. It gives us safe and high speed network transmission.

Uses weak electric fields on the surface of the body as a transmission medium.

Enabling Technology

RedTacton

RedTacton

(1/2)

• It leverages the conductive properties of the human body to transfer data among electronic devices.

• Conceived and patented in the mid-1990s by Neil Gershenfeld and Thomas G. Zimmerman at the MIT Media Lab.

RedTacton

(2/2)

 It is a new HAN technology that uses the surface of the human body as a safe, high speed network transmission path.  Uses the minute electric field emitted on the surface of the human body.  Technically, it is completely distinct from wireless and infrared.

How it Works

(1/3)

How it Works

(2/3)

How it Works

(3/3)

1

The RedTacton transmitter induces a weak electric field on the surface of the body.

2

The electric field sensor (transistor or photonic electric field sensor) detects electric field that reaches the RedTacton receiver.

3

Signals are processed in the receiver circuit and the data is downloaded.

Embedded Receiver

Transmission rate: 10Mbp Protocol: TCP/IP Transmission method: Half-duplex External device interface: 10BASE-T Web page: http://www.redtacton.com

Application of HAN

(1/2)

• One-to-one services : Marketing Application (Context awareness)  Touch advertising & receive detailed information  Inside a shop, shoppers can view related information on their mobile terminals immediately after touching a product.

• Intuitive Operations : private data exchange  And since data can pass from one body to another, you could also exchange electronic business cards by shaking hands

Application of HAN

(2/2)

 Personalization:  Security application

Comparing with other Network Technologies

Personal Digital Cellular Personal Handy-phone System Wideband Code Division Multiple Access Ultra Wideband

Comparison with other network

Conclusion

 Unlike wireless, interception is difficult and security can be considered to be high with RedTacton  When we compare this with other technology present today it can give a better performance over others  It conforms to the “Radio Frequency-Exposure protection Standard (RCR STD-38)” issued by the Association of Radio Industries and Business (ARIB)  Still undergoing development: doesn’t work reliably yet. (common with emergence of new technology)  Supports the vision & future of pervasive computing
